AmesPore® stainless steel candle filters and porous tubes

AmesPore® candle filters and porous tubes are long, cylindrical filters with thin walls, i.e. they have a high length-to-diameter ratio.
The cylinders can be hollow or blind, and have a minimum wall thickness of 1 mm.
The material used for these filters is AISI 316L stainless steel. They are made by isostatic compaction of powder in a flexible mould with the negative shape of the part, and then sintered. The pore size is adjusted by changing the compaction pressure and/or the particle size of the powder.
These filters are commonly used as filter cartridges or aerators for high flow rates. They can be used directly as tubes, or connections of various geometries can be added at the ends (standard or to customer specifi cations).
